WEAR-PLATE FOR RAI LROvAD-Tl ES.

SPECIFICATION forming part of Letters `llatent No. 249,407, datedNovember 8, 1881.

l Application filed April 6, 1881. (No model.) Y

To all whom it may concern:

Be it known that I,DAvrD SERVIs, of the city, county, and State of N ewYork, have invented anew and useful Improvement in Wear- Plates forRailroad-Ties, of which the following is a specification.

Figure l is a plan view of my improvement, illustrating its use. vationof the same, taken through the line .r x, Fig. 1. Figs. 3 and 4 areAperspectiveviews of modiiications of the improvement shown inverted.

Similar letters of reference indicate corre spending parts.

The object of this` invention is to increase' the durability ofrailroad-ties.

In the accompanying drawings, A represents a railroad-rail, and B is atie, sleeper, orother timber upon which the rail A rests.

C is au iron plate of any convenient width, and of such a length as topass beneath" the base of a rail, B, and project at both ends 4beyondthe said rail, as shown in Fig. 1., Upon the lower side of the plate Care formed one or more ilanges, D, which are made thin, so that they canbe driven into the tie or sleeper Blengthwise of the grain of the woodwithout splitting or otherwise materially affecting the timber. Theplates C are designed to be made of such a widththat they will passbetween the spikes E, that secure the bases of the rails to the ties orsleepers 5 or the plates (l can be made wider, as shown in'Fig. 3, inwhich case slots or notches F can be formed in the said plate (l, asshown in Fig. 3, to receive the spikes E. i When the plates Gare to beapplied to the Y ties or sleepers B before they are laid or be- Fig. 2is a sectional elefore the rails A are spiked to them the lian ges D canbe made rectangular or wi th square ends,

- plates C prevent the base ofthe rail from Wearing and cutting thegrain of the Woodand thus destroying the ties or sleepers, so that softwood can be used for ties and sleepers, and Will last until destroyed bydecay. With this construction, also, the flange or ilanges D strengthenthe plates C, so that the said plates can be made light, and so that apressure upon the rails will not bend or curve the plates, the saidpressure putting the said ianges under a tensile strain, which firmlyresists thetendency of the plates to bend.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent- In a Wear-plate for railroad-ties, the flangeor flanges D, formed upon the lower side of the plate G, and beveled orrounded at one end, substantially as herein shown and described, toadapt the wear-plate to be driven in between a rail and a tie or sleeperWithout` displacing the said rail, as set forth.
